------------------------------------------------------------------------------------------------------------------------------------------------------html

孤立詞參考的例子就是yes/no腳本。前端

------------------------------------------------------------------------------------------------------------------------------------------------------python

這裏咱們作10個詞識別實驗，熟悉整條鏈路。git

後續嘗試一些新的模型提升識別率；正則表達式

再嘗試模型語速、語調、平穩噪聲的魯棒性，嘗試已有去噪處理算法的優化前端；算法

擴大孤立詞的數量，裁剪模型，效率優化，熟悉FST解碼器，將嵌入式硬件的孤立詞識別能作到實用層面。shell

最後作連續語音識別、熟悉語言模型。bash

------------------------------------------------------------------------------------------------------------------------------------------------------架構

1、錄製的語料說明ide

在egs/建立本身的項目coffee，再建立s5。

拷貝coffee語音庫以及yes/no如下文件夾和文件。

首先，錄製的語料是關於咖啡的品種，分爲快速、中速、慢速

1)文件夾命名規則:  Modelx_x

 

Model1表示中速

Model2表示快速 

Model3表示慢速 

10個詞，後綴表示表示發音id號

 

2)文件說明

CF_speaker-id_speed_utter-id.wav

CF  coffee，語庫名縮寫

 

 2、腳本修改 

因爲現有的語音庫，詞彙表、目錄結構、語音文件命名、詞典、語言模型，還有對perl不是很熟悉等，因此不少腳本都得從新書寫，順便下python正則表達式。

run.sh
內容以下：
#!/bin/bash

3、實驗流程
 

1.準備好語音庫
 

2.準備好腳本文件
 

local裏面的全部腳本文件。
 

├── create_coffee_labels.py
├── create_coffee_speaker.py
├── create_coffee_test_labels.py
├── create_coffee_test_txt.py
├── create_coffee_txt.py
├── FixUpName.py
├── prepare_data.sh
├── prepare_dict.sh
├── prepare_lm.sh
└── score.sh
 

input裏面的全部文件。
 

.
├── lexicon_nosil.txt
├── lexicon.txt
├── phones.txt
├── task.arpabo
└── trans.txt
 

conf 配置文件夾
 

conf
├── mfcc.conf
└── topo_orig.proto
 

---------------------------------------------------------------------------------------------------------------------------------------------------------------------
 

1.數據準備階段
 

prepare_data.sh 運行完，獲得 text，wav.scp，utt2spk， spk2utt文件，這幾個文件須要保證已排序。
 

 
 
 
  
  text : < uttid > < word >
 
  
  wav.scp : < uttid > < utter_file_path >
 
  
  utt2spk : < uttid > < speakid >
 
  
  spk2utt : < speakid > < uttid >
 
  
  word.txt : 同 text
 
 
 

 

2.準備好詞典，生成語言模型文件
 

input文件夾下：
 

├── lexicon_nosil.txt
├── lexicon.txt
├── phones.txt
└── trans.txt
 

lexicon.txt： 詞典，包括語料中涉及的詞彙與發音。
 

lexicon_nosil.txt 不包含靜音的詞典。
 

phones.txt 全部發音音素
 

trans.txt 訓練的全部詞彙表
 

生成語言模型
 

task.arpabo 用 ngram-count  trans.txt生成。
 

4、碰到的問題
 

1.shell腳本輸出文件名，不能有空格。
 

2.生成語言模型，生成arpa文件，對於孤立詞來講，語言模型沒有意義，這個多是kaldi整個架構的緣由，必需要有語言模型。
 

ngram-count
 

3.文件命名規範，須要進行排序，若是沒有，可能報以下錯誤。
 

 echo "$0: file $1 is not in sorted order or has duplicates" && exit 1;
 

有時加 sort -u 就能夠保證有序 ，可是若是命名不規範，依然報錯，因此本身寫了個腳本，對語音庫文件從新命名。
 

FixUpName.py
